A class constructor in D /is/ inherited automatically. From the spec  
(http://www.digitalmars.com/d/2.0/class.html):
	"If no call to constructors via this or super appear in a constructor,  
and the base class has a constructor, a call to super() is inserted at the  
beginning of the constructor."
If that for some reason does not work (it does for me), file a bug report,  
and use an explicit call to super() in your constructors.

If you're speaking of several non-related classes having identical  
constructors, I'd do it with a mixin.

	template myConstructor
	{
		// do stuff here
	}

	this()
	{
		mixin(myConstructor);
	}

If I have somehow completely missed your point, please do tell.
